Transferred from: bytes MMX commands can be used to accelerate on desktops, but MMX commands are not widely used on arm CPUs. I used a small trick to optimize the Alpha. Alpha mixing is actually very simple. All you need to do is to break down the source color C1, the destination color C2, and then divide the color The numbers R1, G1, B1, R2, G2, and b2 are calculated by the formula (CLR * Alpha + CLR * (32-alpha)/32, respectively, finally, combine them into a color value. However, the computati

Adobe AIR is increasingly favored by desktop application developers for its ease of use and cross-platform support. Today, there are many gorgeous Applications created through Adobe AIR, many of which serve designers and developers. The following describes 16 newly released Adobe AIR programs. They are a good helper for designers and developers: 1. Image sizerImage sizer is a batch graphics processing tool that allows you to scale, optimize, and name

1. The definition word is determined based on the characteristics of the processor.First, arm is a 32-bit processor, so its word is 32-bit. A half word is naturally 16bit;Bytes are 8bit regardless of the CPU.If on MSP430, because it is a 16-bit processor, its word is 16-bit. Half word = byte = 8bit. 2.One word: How many machines are exactly the number of digits,

parameter is a word length, that is, 16 bits. Therefore, it is generally shown in the following format: . Balignw 4, 0x0000d Because the entered content is 16 bits, there are the following situations: 1. If there is no offset for the current address, the address must be in multiples of 4. 2. The current address is offset by 1 byte to meet the requirement

The idea of the C program is roughly to clarify, usually not programming, a lot of minor issues, but fortunately accompanied by a mother-in-law, quickly resolved. Draw a 16-point FFT. This is not an optimized program, but it should be the case for a clear idea. The next step is FPGA. Japanese words are not backed up yet. This week is messy, and every week is messy. Similar to the previous program, the four-point data input is divided into eight equati

Answers to 16 typical interview questions During the interview, the interviewer will ask the applicant, and the applicant's answer will become an important basis for the interviewer to consider whether to accept him.

This article turns from: http://franksinger.iteye.com/blog/614540 In Java, byte is used in binary notation to occupy 8 bits, and we know that each character of the 16 binary needs to be represented by 4-bit bits (23 + 22 + 21 + 20 = 15), so we can convert each byte to two corresponding 16 characters. That is, the high 4 bits of byte and the lower 4 bits are converted to the corresponding
